The %v, %V, %x, and %X format specifiers are available as of MySQL 3.23.8. %f is available as of MySQL 4.1.1.
Ranges for the month and day specifiers begin with zero due to the fact that MySQL permits the storing of incomplete dates such as '2014-00-00' (as of MySQL 3.23).
As of MySQL 4.1.21, the language used for day and month names and abbreviations is controlled by the value of the lc_time_names system variable (Section 9.8, “MySQL Server Locale Support”).
As of MySQL 4.1.23, DATE_FORMAT() returns a string with a character set and collation given by character_set_connection and collation_connection so that it can return month and weekday names containing non-ASCII characters. Before 4.1.23, the return value is a binary string.
mysql>SELECT DATE_FORMAT('2009-10-04 22:23:00', '%W %M %Y');-> 'Sunday October 2009' mysql>SELECT DATE_FORMAT('2007-10-04 22:23:00', '%H:%i:%s');-> '22:23:00' mysql>SELECT DATE_FORMAT('1900-10-04 22:23:00',->'%D %y %a %d %m %b %j');-> '4th 00 Thu 04 10 Oct 277' mysql>SELECT DATE_FORMAT('1997-10-04 22:23:00',->'%H %k %I %r %T %S %w');-> '22 22 10 10:23:00 PM 22:23:00 00 6' mysql>SELECT DATE_FORMAT('1999-01-01', '%X %V');-> '1998 52' mysql>SELECT DATE_FORMAT('2006-06-00', '%d');-> '00'
